Urwah ibn Mas'ud (Arabic: , romanized: 'Urwah ibn Mas'?d) was a Thaqifi chieftain of Taif who became a companion of Muhammad. He was one of the first people from his tribe to accept Islam, and he was killed by his fellow chieftains while preaching Islam in his home city. He was a brother of Barza bint Mas'ud, who married Safwan ibn Umayya.
He was one of the notables of Arabia who entered the negotiations regarding the peace of Hudaybiyah on behalf of Quraysh. He said, "I have visited the kings of Persia, Rome and Abyssinia, but I have not seen any leader more revered and respected by his people than Muhammad. If he ordered them to do anything, they do it without delay. If he performs Ablution (Arabic: , romanized: Wudu') they all seek the remainder of the water he used. They never look at him in the eyes, out of respect."
In a hadith reported in Sahih Muslim, Muhammad mentioned that s? (Arabic: , Jesus) resembled ibn Mas'ud closest in appearance. By descriptions of 'Isa attributed to Muhammed, this would indicate reddish complexion, moderate height and curly, flowing hair.
